Answer:  x = {-1, 1, -i√2, i√2, -3, 4}

Step-by-step explanation:

(x² - 1)(x² + 2)(x + 3)(x - 4)(x+1)=0

Set each factor equal to zero and solve.

x² - 1 = 0  →  x² = 1  →  x = ±1

x² + 2 = 0  →  x² = -2  →  x = ± i√2

x + 3 = 0  →  x = -3

x - 4 = 0  →  x = 4

x + 1 = 0  →  x = -1   (note that -1 is a duplicate - solved from the first factor)

Answer:

Answer:  x = {-1, 1, -i√2, i√2, -3, 4}

Points "in common with the x-axis" are also known as the roots of the quadratic equation [tex]x^2-12x+12=0[/tex]. You can apply the quadratic root formula to determine the roots, and also to determine how many such roots there are. With a quadratic (whose graph is a parabola), there can be maximum of 2 roots. But under certain circumstances, there may be only one or no such root.

The root formula for a generic quadratic [tex]ax^2+bx+c[/tex] is as follows:

[tex]x_{1,2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

The expression [tex]b^2-4ac[/tex] under the square root is called the determinant. It is called so because it determines the number of real roots. If the determinant value is > 0, there will be 2 roots (and so the parabola will cross the x-axis in 2 points), if its value is =0, there will be only a single root (the the parabola will touch the x-axis in exactly one point), and, finally, if its value is < 0, the quadratic has no real root (andthe parabola will not have any x-intercepts).

So, let's take a look:

[tex]b^2-4ac= (-12)^2-4\cdot 1\cdot12=96[/tex]

This means the parabola will intercept the x-axis at 2 points, two real roots.

Since the coefficient of the quadratic term is positive (a=1), the parabola is oriented "open-up." But since we already know the parabola intercepts in two points, the fact that it is open-up implies now that the vertex must lie below the x-axis (otherwise it could not intercept it).

The number of common points between a parabola and the x-axis is determined by the discriminant of its equation, while the position of its vertex relative to the x-axis is determined by the value of y at the vertex. A positive discriminant yields two points of intersection, zero yields one, and negative yields none. The vertex's position can be above, on, or below the x-axis depending on whether k in its vertex form is positive, zero, or negative.

To determine how many points a parabola has in common with the x-axis, we look for the solutions to the parabolic equation when y is set to zero. The number of intersections corresponds to the number of real solutions to this equation. If the parabola's equation is given in the standard form y = ax2 + bx + c, we can use the discriminant (b2 - 4ac) to find out how many times the parabola touches the x-axis. If the discriminant is positive, the parabola intersects the x-axis at two distinct points; if it is zero, the parabola touches the x-axis at exactly one point (the vertex); and if it is negative, the parabola does not intersect the x-axis at all.

The vertex of the parabola lies above, on, or below the x-axis depending on the value of y at the vertex. In the vertex form of a parabola, y = a(x - h)2 + k, where (h, k) is the vertex, if k is positive, the vertex lies above the x-axis; if k is zero, the vertex is on the x-axis; and if k is negative, the vertex lies below the x-axis. Typically, the coefficient a determines the direction of the parabola opening—upwards if a is positive, and downwards if a is negative, but this does not affect the vertical placement of the vertex relative to the x-axis.

the answer is 28

Answer:   b) (x - 2)(x + 1)(x + 3) = 0

Step-by-step explanation:

Look at the graph to find the x-intercepts (where the graph crosses the x-axis).

x = 2,       x = -1,      and   x = -3

Rewrite them as factors:

x - 2 = 0,  x + 1 = 0, and  x + 3 = 0

Combine the factors through multiplication:

(x - 2) (x + 1) (x + 3) = 0

16 - 7 = 9

For every 3 terms, you add 9.

Divide, to find the amount you add for 1 terms.

3 / 3 = 1

9 / 3 = 3

For every 1 terms, you add 3.

[tex]s_{1}[/tex]= 7

Answer:

8c > 21

The solution is c > 21/8.

Step-by-step explanation:

Not all math problems have only one solution. Some math problems have multiple solutions such as set or group of solutions. These problems are called inequalities. Inequalities have solutions within a range using symbols such as >, <, ≤, and ≥. These are known as greater than, less than, less than or equal and greater than or equal. You can write any inequality expression from words into symbols using these signs.

The expression "the product of c and 8 is greater than 21​" is translated into

8c > 21

since product is multiplication.

It can be solved by dividing both sides by 8.

The solution is c > 21/8.

when all goes wrong...choose c my friend.

Answer:

[tex]4(3\frac{2}{5})[/tex] is greater

Step-by-step explanation:

step 1

we have

[tex]4(3\frac{2}{5})[/tex]

convert to an improper fraction

[tex]3\frac{2}{5}=\frac{3*5+2}{5}=\frac{17}{5}[/tex]

so

[tex]4(3\frac{2}{5})=4(\frac{17}{5})=\frac{68}{5}[/tex]

step 2

we have

[tex]3(4\frac{2}{5})[/tex]

convert to an improper fraction

[tex]4\frac{2}{5}=\frac{4*5+2}{5}=\frac{22}{5}[/tex]

so

[tex]3(4\frac{2}{5})=3(\frac{22}{5})=\frac{66}{5}[/tex]

therefore

[tex]4(3\frac{2}{5})[/tex] is greater

Final answer:

After converting mixed numbers to improper fractions and multiplying, it is clear that 4 x [tex]3\frac{2}{5}[/tex] is greater than 3 x [tex]4\frac{2}{5}[/tex].

Explanation:

The question asks which is greater: 4 x [tex]3\frac{2}{5}[/tex] or 3 x [tex]4\frac{2}{5}[/tex]. Let's compare these two expressions

First, convert the mixed numbers to improper fractions:

[tex]3\frac{2}{5}[/tex] = (3x5 + 2)/5 = 17/5

[tex]4\frac{2}{5}[/tex] = (4x5 + 2)/5 = 22/5

Next, multiply each by the whole number:

4 x 17/5 = 68/5 = 13.6

3 x 22/5 = 66/5 = 13.2

Therefore, 4 x [tex]3\frac{2}{5}[/tex] is greater than 3 x [tex]4\frac{2}{5}[/tex].

This is valid.

Answer:

1/2

Step-by-step explanation:

if the one line's slope is m = –2, then the perpendicular line's slope will be m= 1/2 (the slope of a perpendicular line is the reciprocal of the slope of the first line)

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

I will call [tex]m_{a}[/tex] the slope of line [tex]a[/tex], and [tex]m_{b}[/tex] the slope of line [tex]b[/tex].

For two lines to be perpendicular, the following must be satisfied:

[tex]m_{a}*m_{b}=-1[/tex]

in this case we know:

[tex]m_{a}=-2[/tex]

so:

[tex](-2)*m_{b}=-1[/tex]

And clearing for the slope of line [tex]b[/tex]:

[tex]m_{b}=\frac{-1}{-2} \\m_{b}=\frac{1}{2}[/tex]

The slope of the line [tex]b[/tex] which is perpendicular to line [tex]a[/tex] is [tex]\frac{1}{2}[/tex]

Answer:

y = 6

Step-by-step explanation:

Given

y = [tex]\frac{3}{4}[/tex] x + 3 and (4, ? )

Substitute the x- coordinate x = 4 into the equation for corresponding value of the y- coordinate.

x = 4 : y = [tex]\frac{3}{4}[/tex] × 4 + 3 = 3 + 3 = 6

Hence the coordinate point is (4, 6)

Answer:

y+2 = 2/3(x+1)

y= 2/3x - 4/3

Step-by-step explanation:

If we want a line parallel to  y=2/3x+7, it will have the same slope

m = 2/3

We have a point (-1,-2), so we can use point slope form

y-y1 = m(x-x1)

y--2 = 2/3(x--1)

y+2 = 2/3(x+1)

If we want the line in slope intercept form, distribute the slope

y+2 = 2/3 x +2/3

Subtract 2 from each side

y+2-2=2/3x +2/3-2

y = 2/3x +2/3 - 6/3

y= 2/3x - 4/3

Answer: OPTION D

Step-by-step explanation:

To solve this problem you must apply the formula for calculate  the surface area of the rectangular prism:

[tex]SA=2(wh+lw+lh)[/tex]

Where w is the width, h is the heigh and l is the lenght.

Based on the rectangular prism shown, you have that:

[tex]w=9.08cm\\h=3.23cm\\l=11.73cm[/tex]

Finally when you substitute values into the formula you obtain the following result:

[tex]SA=2[(9.08cm*3.23cm)+(11.73cm*9.08cm)+(11.73cm*3.23cm)]=347.45cm^2[/tex]

Answer:

D

Step-by-step explanation:

The surface area is the area of all the surfaces, together.

A rectangular prism has 6 rectangular surfaces. We need to add those 6 faces and sum it.

Area = 2 ( 3.23 * 9.08 ) = 58.6568

Area = 2 ( 3.23 * 11.73 ) = 75.7758

Area = 2 ( 11.73 * 9.08 ) = 213.0168

Summing all of them up,

Surface area of Rectangular Prism = 58.6568 + 75.7758 + 213.0168

=347.4494

* Rounding to nearest hundredth, 347.45 cm ^2

Answer:

1.58

Step-by-step explanation:

Okay. We're solving for t because we need to know how many seconds. From the problem, we know the height (10), but we don't know when that height happens.

[tex]10 = -16tx^{2} -7t+61[/tex]

We can factor by multiplying -16 by 61 first to get -976 and see what multiplies to get -976 AND adds to get -7 at the same time. But we can also use the quadratic formula because, let's be honest, factoring can be a lot of extra work.

[tex]10 = -16t^{2} -7t+61\\\\0 = -16t^{2} -7t+51\\\\t=\frac{-b\pm \sqrt{b^{2}-4ac } }{2a} \\=\frac{-(-7)\pm \sqrt{(-7)^{2}-4(-16)(51) } }{2(-16)} \\=\frac{7\pm \sqrt{49+64(51) } }{-32} \\=\frac{7\pm \sqrt{3313} }{-32}[/tex]

Plug both the plus and the minus versions into your calculator and...

[tex]t\approx -2.02, 1.58[/tex]

There's no such thing as negative time, so -2.02 is automatically disqualified, leaving 1.58 as the answer.

Hope this helps, let me know if I missed anything!

The time takes for the egg to reach the height 10 feet from the ground on the basis of the given quadratic equation will be 1.58 seconds.

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.

For example, 3x² + 6x + 8 = 0 here x has the highest term as 2 and the coefficient of x² is not zero.

As per the given quadratic equation,

d = - 16t² - 7t + 61

The time t in seconds at d = 10

-16t² - 7t + 61 = 10

16t² + 7t - 51 = 0

The roots of the above quadratic equation will be,

t = [-7 ± √(7² - 4 × 16 × -51 )] /(2 × 16)

t = (-7 ± 57.586)32

t = 1.58 or -2.02

Since, time is always positive thus, t = 1.58 seconds.

Hence "The time takes for the egg to reach the height 10 feet from the ground on the basis of the given quadratic equation will be 1.58 seconds".
